The seats were really comfortable. Flight crew were friendly with passengers. Overall was a great flight.

Arrived early, comfortable seats (Comfort+). Mediocre food, poor wifi (intermittent).

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Flight was great! This flight from Atlanta was even better than when I paid for Comfort from SNA to Atlanta.

Great crew, flight on time, luggage pick up a breeze

Was on time, normal boarding. The worst flight attendents and service I ever seen,, can't believe Delta can have such service. Bathroom was dirty and no toilet paper, paper towels and used toilet paper all over the floor, when I tried to tell flight attendant she didn't even let me to finish and turn around. Very rude. Wi fi didn't work.

Connection flights should be spaced out farther because too close I missed my connection.

Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.

On time! There were plenty of airport employees who were able to keep us moving in the right direction. The crew on the plane were professional.

Left /arrived on time. Decent seat space. Like the wifi/plugs and entertainment. Windows and tray table were kinda gross. Attendants didn't start snack service til 40mins before landing. Two rows before us, captain came on to say there's turbulence and recalled staff to seats. So, no drink/snack. Later, attendants didn't stop to see if we had trash nor even look our way. Felt invisible! Almost all pilot announcements were not only unintelligible, but so quiet. We had no idea what she said.

As always, most AA flights that we fly are almost ALWAYS delayed and that too multiple times. Very frustrating

Boarding was smooth and seamless and the flight was without incident.

Very hard to beat a British Airways international flight…the crews are always so amazing! One flight attendant that really stood out was Emma…she was very personable and accommodating with any request we had!!

Our flight was repeatedly delayed for maintenance problems: scheduled for 9.30am, eventually delayed to 7pm! Very very inconvenient! AA should have provided a substitute plane much earlier.. On the other hand, Customer Service crew in Charlotte helped us to reach NY (LGA) by late afternoon. Thank you Patricia!! The actual flight was quick and very comfortable. As always a. excellent, professional crew. [no food on a a short hop).

Take-off delayed an hour because of a missing flight officer, so,arrived in Charlotte lates causing many passengers to miss connections. Otherwise a very good flight, safe and comfortable, with an excellent professional crew.

Little time between flight from Dallas to flight to Gainesville. We chose this one, 43 minutes between, because the price for a connection with at least an hour between, was so much higher. Had to ask passengers on the Dallas flight to please allow us to deplane ahead of them. The economy passengers allowed this. We had to walk very fast to the next gate, 35 gates away. Thankfully all in the same terminal. Getting to the small Gainesville plane was a little confusing as you enter an area that is boarding many small planes at the same time. We stood in the wrong line for about 15 seconds before realizing it was not our Gainesville flight. Since I had boarded at this gate in the past, I knew to check the signs carefully so we weren’t lost. The first class seat experience was wonderful. I really enjoyed the upgrade. We were offered an alcohol drink as soon as we sat down. I got something different but it was a great gesture especially since we really had to hurry to make the flight. We had packed expecting we might miss this connection, but made it. Our luggage didn’t miss the flight. American Airlines delivered our bags to our home the next day. That was very convenient!

The plane was large, not full, but one with 3 seats near each window and 4 in a row in the middle of the plane. There were screens on the backs of the seats for entertainment and information. To use the entertainment one needs ear plugs that physically plug into the screen. My husband had some he let me use as I only had blue tooth type. The stewards gave out some headphones to some, but when my neighbor asked for some, the steward said no. So maybe they ran out? Idk. Bring the old kind of headphones or earbuds if you want entertainment in case this is the type of entertainment offered. We had a very tight connection in Miami. 43 minutes. The other economy passengers allowed us to get ahead of them because I asked if we could since we were near boarding time for our next flight and 35 gates away. They were extremely kind. First class wasn’t going to allow us to pass through. We did make the next flight. Our baggage didn’t, but they were delivered to us the next day and we were prepared with essentials in our carry on packs.

Food is what you expect on a plane. Nothing gluten free. But that is expected. Drinks, apple juice, was fine. Seat, what I expected. Fine.

This was my first flight on Aer Lingus and it was great. The plane wasn't full so I could move to a seat with extra room. The food was pretty good for airline food and the staff was nice and attentive. I enjoyed the media provided during my 10 hour flight. We arrived home early and it's always good to be home!

Everything went as planned. The only issue I had was with the gate C31 attendant. The person could barely speak English and was very difficult to understand.
